“…OR,4.20;CI,). This can be associated with the fact that the infective capacity of the ovum of H. gallinarum and A. galli is progressively reduced when exposed to the adverse effects of environmental conditions (SMITH, 1998;MERCADO et al, 2004). Moreover, elevated soil temperatures have been associated with reduced infectivity of the eggs of H. gallinarum and A. galli (CHRISTENSON et al, 1942;TARBIAT, 2012), while desiccation was considered as detrimental to the viability of the eggs of A. galli (CARDOZO;YAMAMURA, 2004;TARBIAT, 2012).…”

The effects of managerial systems on the occurrence of gastrointestinal helminths in Free-Range Chickens (FRCs) from northern Paraná, Brazil were investigated. The most predominant (23.3%; 61/262) cestode observed was Raillietina cesticillus; Heterakis gallinarum (71.4%; 187/262) and Ascaridia galli (45%; 118/262) were the predominant nematodes; Postharmostomum commutatum was the only trematode observed in 2.7% (7/262) of FRCs. The most elevated parasitic burdens were associated with Heterakis gallinarum, Ascaridia galli, and Raillietina cesticillus. Significant (p ≤ 0.05) associations were observed when the effects of the types of bedding, soil type, and fence restriction of FRCs were considered relative to the possibility of helminthiasis.

“…Sin embargo, existen casos reportados en Perú en los cuales no se encontró el antecedente epidemiológico de viajes a zonas endémicas 6,8,9 . Así mismo, en un estudio realizado en Chile para evaluar la presencia de agentes causantes de larva migrans cutánea en muestras de heces caninas, se encontró la presencia de larvas de ancylostomideos en 9,5% de las muestras, en 8 de las 13 ciudades incluidas 14 . Esto puede indicar que algunos países de Sudamérica, a pesar de no ser endémicos de esta parasitosis, pueden tener algunas zonas con riesgo de transmisión de larva migrans cutánea.…”

Cutaneous larva migrans after a trip to the Caribean Cutaneous larva migrans is a parasitic disease caused by Ancylostoma braziliense and Ancylostoma caninum larvae, which is transmitted by contact with sand infested with these parasites. Dogs and cats are the definitive hosts. This parasitic disease is endemic in the Caribbean, Africa, Australia, and Asia. We present the case of a 27-year-old woman, who developed skin lesions compatible with cutaneous larva migrans on her right foot after returning from beach vacations in the Mexican Caribbean. After clinical diagnosis, oral ivermectin was administered, with good clinical response.Key words: Cutaneous larva migrans, travel medicine Palabras clave: Larva migrans cutánea, medicina del viajero. IntroducciónL a larva migrans cutánea es una parasitosis ocasionada principalmente por las larvas de Ancylostoma braziliense y Ancylostoma caninum. Los perros y gatos son los hospederos definitivos, los que depositan sus heces infestadas con huevos contaminando la arena de las playas. Las larvas posteriormente eclosionan por la humedad y el calor. Los seres humanos son afectados por esta enfermedad al tener contacto directo con la arena, como ocurre al caminar con los pies descalzos [1][2][3][4] . El ingreso de las larvas a la piel ocasiona lesiones serpiginosas, eritematosas, levemente solevantadas 5,6 . El diagnóstico de larva migrans cutánea es clínico, dado que las lesiones son muy características. En algunas ocasiones se pueden observar flictenas, edema de la extremidad afectada o puede complicarse con una sobreinfección bacteriana secundaria al grataje 2,7 . Incluso pueden simular otras patologías como herpes zoster 8 . El tiempo de presentación de las lesiones es entre uno a cinco días, sin embargo, se han comunicado casos de hasta varios meses tras la exposición. El sitio más frecuente de aparición de las lesiones son los miembros inferiores 1,4 . En Perú, larva migrans es una entidad poco frecuente 6,8,9 . Se presenta el siguiente caso clínico como diagnóstico diferencial entre las enfermedades del viajero [10][11][12] . Caso clínicoMujer de 27 años de edad, peruana, procedente de Lima, consultó por múltiples lesiones en la piel del pie derecho, pruriginosas, de 10 días de evolución. Posteriormente se asoció edema de la extremidad y malestar general, dos días previos a la evaluación. Como antecedente, la paciente había visitado Tulum (Riviera Maya, México) durante dos días, en que caminó descalza en la arena y practicó buceo, además de haber sufrido múltiples picaduras por mosquitos en las extremidades inferiores. Había retornado a Lima dos semanas antes de consultar.Al examen físico, la paciente presentaba múltiples lesiones serpiginosas, solevantadas, eritematosas, confluentes, de uno a tres centímetros de longitud y de uno a dos milímetros de espesor, en el dorso y 2°, 3° y 4° ortejos del pie derecho. Además, en los dedos se observaban pequeñas vesículas pruriginosas (Figura 1).Se realizó el diagnóstico clínico de larva migrans cutánea y se indicó tratamiento co...

“…Several studies 4,5,16 have been conducted on soil contamination with eggs, cysts, oocysts, and larvae of zoonotic parasites in public places of leisure, such as squares and parks. In this study, conducted in the squares of Belo Horizonte, we observed the presence of a large number of owned and stray dogs, which may explain the significant amount of feces in the environment.…”

SUMMARYTo evaluate soil contamination by parasites in different developmental stages in public squares used as recreation and leisure areas for children in Belo Horizonte (MG, Brazil), 210 soil samples and 141 canine fecal samples were collected from 42 squares in the city. These samples were analyzed by the Caldwell and Caldwell technique and the Hoffman, Pons, and Janer technique. Of the samples analyzed, 89 (42.4%) soil samples and 104 (73.5%) fecal samples were contaminated with Ancylostoma sp., Toxocara sp., Trichuris sp., or Dipylidium sp. eggs; Giardia sp. cysts; or Isospora sp. oocysts. The commonest parasite was Ancylostoma sp., found in 85% soil and 99% fecal samples, followed by Toxocara sp., found in 43.7% soil and 30.7% fecal samples.
